When a container registry has many tags, it's easy for the DELETE call to take more
than 60 seconds and fail. This can also leave the registry in a bad state with
null bytes since some of the images have been deleted with tags still pointing to them.
In addition, we have to prevent users from accidentally initiating the delete multiple
times or this could leave the registry with orphaned tags.

This commit also adds a flash message to notify the user the registry is scheduled
for deletion.

When using ruby interpolation in externalized strings, they can't be
detected. Which means they will never be presented to be translated.

To mix variables into translations we need to use `sprintf`
instead.

Instead of:

    _("Hello #{subject}")

Use:

    _("Hello %{subject}) % { subject: 'world' }
